Nancy, George, and Bess can't wait to check out the new petting zoo that has opened in River Heights, and especially the cute Shetland pony named Buttons. But it looks like they might not have to wait very long--this pony has a habit of escaping from his pen and showing up all over town! He's getting quite a reputation for eating the flowers in everyone's front lawns. Nancy secretly wishes Buttons would show up on her lawn, but she also knows that it's very important he stays put. The trouble is, no one knows how he's getting out. Sounds like it's time for the Clue Crew to saddle up and settle this pony problem! Recommended for ages 6 to 9.
